validate.js

validate.js is a lightweight JavaScript form validation library inspired by CodeIgniter.

Features

  • Validate form fields from over a dozen rules
  • No dependencies
  • Customizable Messages
  • Supply your own validation callbacks for custom rules
  • Chainable customization methods for ease of declaration
  • Works in all major browsers, (even IE6!)
  • Modeled off the CodeIgniter form validation API

How to use

    var validator = new FormValidator('example_form', [{
        name: 'req',
        display: 'required',
        rules: 'required'
    }, {
        name: 'alphanumeric',
        rules: 'alpha_numeric'
    }, {
        name: 'password',
        rules: 'required'
    }, {
        name: 'password_confirm',
        display: 'password confirmation',
        rules: 'required|matches[password]'
    }, {
        name: 'email',
        rules: 'valid_email'
    }, {
        name: 'minlength',
        display: 'min length',
        rules: 'min_length[8]'
    }, {
        names: ['fname', 'lname'],
        rules: 'required|alpha'
    }], function(errors) {
        if (errors.length > 0) {
            // Show the errors
        }
    });
